1 Claim.

.f The present invention relates general Yto shipping and/or storingvessels and has particular reference to a carboy or like lcontainer forlshipping and/or storing liquids ror .solids under sanitary andotherrdesirable conditions which prevail when a glassmor othernon-'corrosive materielle-,used as a receptacle One of the importantfeatures of the invention resides in the provision of means forprotecting a. glass or other fragile vessel when in transit or whenstored so that the ordinary abuse to which the receptacle is subjectedwill not injure or otherwise destroy the same.

Another featureof the invention resides in the construction of a glassor other'non-corrosive vessel which is adapted to contain materials forstoring or shipping purposes and in which the materials are containedwithin such a vessel in an insulated condition so that the changes intemperature will not affect the qualities of the stored material, atleast to the extent that Such changes in temperature as may be expectedunder ordinary shipping and storing conditions will necessarily make achange in the condition of the material. In this connection we areparticularly concerned with shipping and storing such liquids whichrequire a more or less critical temperature between the time they areplaced in the carboy and dispensed therefrom.

Due to the fragile qualities of such a container it becomes necessary toprotect the same against handling abuses and it is therefore anotherobject of the invention to construct a shipping and storing vessel in amanner to realize these advantages without increasing the cost ofconstruction to a prohibited extent.

With these and other objects in view, which will be apparent from thefollowing detailed description of the accompanying drawing We will nowproceed to describe the construction of the invention with reference tothe illustrative embodiment shown in the accompanying drawing.

In said drawing:

Fig. 1 is a view in vertical section of a carboy showing how theinvention may be utilized for acid or the like containers;

Fig. 2 is a view similar to Fig. 1 but showing a modified form of thecarboy and Fig. 3 is a view in detail of still another modified form ofcarboy. l

Referring now to the drawing in detail and with particular reference toFig. 1, 5 represents a double wall metallic shell the outer wall 6 ofwhich, at the lower portion is turned outwardly to leave an olfsetflange 'I around which the edge 1935, Serial No. 31,471 (Cl. 220-10) ofythe bottom 8 is turned so as to join therewith. The upper end of theouter wall has a` similar oliset iiange 9 around which v`the cover I0 isturned. The inner wall vI IA .of the shell is preferably fashioned withan integral bottom I2 which vrests upon the circular corner seat I3.This seat Aalso serves as a spacer for the inner wall and is made vfromrubber or the like 'material so as to provide the desired resilientprotective cushion. This cushion is confined in place by upsetting thecenter area of the bottom so as to leave a restricted circular confineadjacent the outer Wall 6. The open top of the inner wall abuts againstthe under side of the cover I0 at approximately the point where theshoulder I4 merges with the incline.

As additional spacing means for the double Walls of the shell and at thesame time provide resilient protective cushions, weY employ circularrings I5 which are seated in the depressions or grooves made bycorrugating the outer wall at spaced intervals.

Housed with the shell 5 is the non-corrosive inner container I6. Thiscontainer is molded from some material suitable for the purpose and thesame is embedded in an asphalt composition I'I which completelyenvelopes the same excepting the projecting portion I8 of the neck. Thiscomposition is poured in the space between the container I6 and theinner Wall of the shell and fills the entire space around the container.This provides a protective covering for the container which alsoco-operates with the space between the walls of the shell to heatinsulate the container.

The form in which the container is molded is of some importance becauseit provides for an increased thickness ofthe asphalt composition atlocations where it is most desirable, for instance at the lower edge,the central portion of the bote tom and over the top. It is of courseunderstood that the asphalt composition is poured before the cover isset in place or else a pouring opening may be made in either the coveror the bottom of the shell. i

'Ihe cover I0 is made with an opening to admit the neck I8 and the edgeof the opening snuglyy fits the shoulder I9 on the neck.

In Fig. 2 we have illustrated a modified forni.

In this type the inner container, is substantially the same design butthe shell is made with a single wall 20. The top or cover 2I is formedas an integral part of the shell. Like the cover I0 v the edge of theopening in the cover which adaround the shoulder 22.

The bottom 23 is separately formed and joined to the side Wall of theshell like the bottom Y8. 24 represents a rubber or the like circularsupporting rim 24 for the base of the carboy.

While this rim is 'molded to snugly fit the base of the carboy bolts,rivets or the like'25 may be used at spaced intervals to hold theriminplace.

The outside of the shell in this form is equipped with circular rubberor 4the like bumpers 26 as a protective measure. These bumpers encirclethe shell just below the 'offset corrugations 21.

In Fig. 2 the asphalt composition is poured when the carboy is invertedand before the bottom 23 is set in place or else a pouring opening isprovided through either the top or bottom.

In Fig. 3 we are illustrating a modified form of base.V Here both thebottom 28 and the side 129 are extended outwardly to provide an offsetprojection. They are joined together at their extremities by curling onearound the other. A relatively thick band of rubber 3l is appli'ed'toserve as a supporting base and shock absorbing bumper.

Where we have used the Words glass or nonmits the neck I8 of thecontainer fits snuglyV corrosiveV as a descriptiveterm for explainingthe nature and physical properties of the inner container it should beunderstood that we have Y in mind using not only glass but also potteryor other ceramic materials, enamel ware or even stainless steel. It istherefore pointed out that when we speak o non-corrosive material in thedescription and claim vwe wish Vthe same to be `interpreted as anymaterial suitable for the purpose having the qualities described.

VI-laving thus described an embodiment of our invention what we claimand wish to secure by Letters Patent of the United States is:

A carboy orY the like receptacle comprisingV an Youter shell and aninner non-corrosive container spaced within said shell with the spacetherebetween lled with a poured protective substance, vsaid containerbeing fashioned with its upper*r portion Vpresenting a relatively thickand abrupt offset shoulder leaving a substantial concave area inwardlyof the shoulder to thereby enlarge the space between itV and the outershell for accommodating an increase in the thickness of. the pouredprotective substance at this particularV location.
